摘要
考虑系统安装的地理位置、使用时间、环境温度和系统热负荷等因素对热水系统集热量影响,给出太阳集热器最佳倾角的确定方法,并以上海临港地区为例进行计算机仿真与实验。结果表明,在太阳能热水系统补充热量最小的倾角时,才能更有效地利用冬季的太阳能资源,从而实现全年太阳能的最大利用,达到节能减排的效果。
Based on location, usage time, environment temperature of the project installing solar collector, the tilt angle of collector could be set as the same as the local latitude in view of maximizing solar contribution. However, solar water heaters with annually maximum solar contribution possess poor performance in winter. Taken account of installation location, utilization time, ambient temperatures and thermal load of system and so on, the method to calculate the optimum tilt angle of solar collectors was presented based upon minimum auxiliary energy. Shanghai was taken as the example to carry out the simulation experiment, and the results show that the angle of acceptance relatively improved the annual solar contribution and finally achieved energy-saving and emission-reduction.
